Problem

When generating an electronic tax return there is a validation warning "Sum of box 172 and box 173 must not exceed the apportioned AIA limit" This valdiation occurs even though the increase in AIA is entered correctly in the data entry screen for capital allowances with no restrictions given. This validation will occur if returns with a period end date after 31/03/14 are using the new £500,000 AIA limit.

Resolution

This is caused by a HMRC validation update which has been included in version 11.6.0 which is currently available on our website. Please regenerate the electronic return after upgrading to version 11.6 and it will clear the validation and transmit successfully.
